Happy BDay, Mary! Hope you enjoy the outing today.
You're doing so many of the right things... hiring caregivers, going to therapists, respite time with friends, getting away from the house and your LO for periods of time, the plan to move in a couple of months, soon joining a support group, your connections here, etc.
All the above will certainly help get you through the challenges of caregiving. You're so wise to have taken these steps. They'll all assist in keeping you healthy and strong so you can better handle upcoming events and emotions that will inevitably arise as your hubby progresses with his disease.
All the best!
